  ****************************************************************
  The problem occurs when sending an invalid SIP message to the
  application server, over a TCP or TLS connection. The message
  is invalid if its header contains a byte value larger than 127,
  which is not a UTF-8 character. This causes the SIP container
  to stop processing the message, and all messages that follow,
  over the same connection, including valid messages.
  

Problem conclusion

• The problem is fixed in the SIP container. With this fix, the
  container drops the invalid message, and closes down the
  connection. If the invalid message is a request, the server
  replies to it with a 400 (Bad Request) response.
  This allows the client to create a new connection and send
  future messages over the new connection.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.13 for the Feature Pack for Communications
  Enabled Applications. Please refer to the Recommended Updates
